Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“Write server code once, deploy anywhere. The preset system handles platform-specific deployment automatically.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“UnJS is building the invisible infrastructure of the JavaScript ecosystem. Nitro's portability is genuinely valuable.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“Universal server engines that abstract deployment targets are the right foundation for framework-agnostic backends.”
